The opinion of Aventure Nordique

The Black Diamond Cosmo 350 is a 350 lumen headlamp that will suit lightweight enthusiasts looking for a durable and versatile light. You can power this headlamp with 3 AAA batteries included or pair it with the BD 1500 rechargeable battery (sold separately) to further boost the light's life.

With an IPX8 waterproof rating, it will perform well after an aquatic submersion of less than 30 minutes at a maximum depth of 1 meter. It will not fail during your treks where the weather is capricious and will illuminate you in full power on more than 60 meters.

It is equipped with a dimmer switch and can assist you when you want to remain discreet at night thanks to the red LED night vision mode which also has a dimmer switch and a flashing mode.

A facet reflector will allow you to optimize energy consumption.
